Our Verdict

Zinus Original Green Tea 2024

Novaform ComfortGrande Plus

The Novaform ComfortGrande Plus is better than the Zinus Original Green Tea 2024. The Novaform is more responsive, so you're less likely to feel stuck in place, and it has better motion isolation, so you're less likely to feel your partner's movements. Its sturdier edges make it more comfortable to sit or sleep on the side of the bed.
